feat(frontend/copilot): add per-turn work-done summary stats (#12257)

## Summary
- Adds per-turn work-done counters (e.g. "3 searches", "1 agent run")
shown as plain text on the final assistant message of each
user/assistant interaction pair
- Counters aggregate tool calls by category (searches, agents run,
blocks run, agents created/edited, agents scheduled)
- Copy and TTS actions now appear only on the final assistant message
per turn, with text aggregated from all assistant messages in that turn
- Removes the global JobStatsBar above the chat input

Resolves: SECRT-2026

## Test plan
- [ ] Work-done counters appear only on the last assistant message of
each turn (not on intermediate assistant messages)
- [ ] Counters increment correctly as tool call parts appear in messages
- [ ] Internal operations (add_understanding, search_docs, get_doc_page,
find_block) are NOT counted
- [ ] Max 3 counter categories shown, sorted by volume
- [ ] Copy/TTS actions appear only on the final assistant message per
turn
- [ ] Copy/TTS aggregate text from all assistant messages in the turn
- [ ] No counters or actions shown while streaming is still in progress
- [ ] No type errors, lint errors, or format issues introduced
